Description
Technical field
The present invention relates to a kind of sensor, especially a kind of temperature sensor of automatic telescopic.
Background technology
Temperature sensor includes protection pipe, connector sleeve, terminal box, and temperature element, thermometric are equipped in protection tube cavity lower end
Element is connect by the conducting wire in protection pipe with terminal box, and terminal box is mounted on the upper end of protection pipe, by connector sleeve by temperature
Sensor is installed in equipment, and protection pipe lower end is made to be contacted with measured part.The sensor protection pipe of this structure is relative to even
Female connector cannot have axial displacement, and hard contact is belonged in use, fragile, be likely to occur when having vibration or stress situation and mutually divide
From the case where, temperature signal collection is not accurate.
Invention content
The object of the present invention is to provide a kind of simple in structure, peace by when can keep having between protection pipe end and measured part
When thering is stress to change situation during certain contact force, use protection pipe relative to connector sleeve automatically retractable, remain
Contact, collecting temperature signal accurately automatic telescopic temperature sensor.
The temperature sensor of the automatic telescopic of the present invention, including protection pipe, connector sleeve, terminal box, in the case where protecting tube cavity
End is equipped with temperature element, and temperature element is connect by the conducting wire in protection pipe with terminal box, and terminal box is mounted on the upper of protection pipe
End；Snap ring is equipped at the endoporus upper step of connector sleeve, the upper end of connector sleeve has upper external screw thread, the lower end of connector sleeve to have lower outer spiral shell
Line is mutually furnished with nut with upper external screw thread, spring is equipped between the step and snap ring of nut inner hole, is terminated under connector sleeve
Casing, protection pipe are inserted into the centre bore of nut, spring, connector sleeve, snap ring, casing, and snap ring is relatively fixed with protection pipe and connect,
It is located at lower external screw thread upper end on the outside of connector sleeve and is equipped with gasket, sealing ring is equipped between protection pipe and casing.
The temperature sensor of the automatic telescopic of the present invention, when installation, are connected by the lower external screw thread of connector sleeve with equipment, are made
Protection pipe lower end is contacted with measured part, and spring has a certain amount of compression, snap ring and protection pipe relative to even after contact
Female connector has a certain amount of axial displacement, ensure that protection pipe is in contact condition always with measured part, is hardly damaged, temperature letter
Number acquisition is accurate.
Description of the drawings
Fig. 1 is the structural schematic diagram of the specific embodiment of the invention.
Fig. 2 is nut shown in FIG. 1, the schematic cross-sectional view at connector sleeve.
Specific implementation mode
As shown in Figure 1, 2：The temperature sensor of the automatic telescopic of the present invention, including protection pipe 9, connector sleeve 5, terminal box
11, it is equipped with temperature element in 9 inner cavity lower end of protection pipe, temperature element passes through conducting wire and terminal box 11 in protection pipe, terminal box
11 are mounted on the upper end of protection pipe 9.Snap ring 4 is equipped at the endoporus upper step of connector sleeve 5, there is upper outer spiral shell in the upper end of connector sleeve 5
There is lower external screw thread 7 in the lower end of line 3, connector sleeve 5, is furnished with nut 1 with 3 phase of upper external screw thread, in step and the snap ring 4 of 1 endoporus of nut
Between be equipped with spring 2, be terminated with casing 10 under connector sleeve 5.Protection pipe 9 be inserted into nut 1, spring 2, connector sleeve 5, snap ring 4,
In the centre bore of casing 10, snap ring 4 is relatively fixed with protection pipe 9 and connect.It is set positioned at 7 upper end of lower external screw thread in 5 outside of connector sleeve
There is gasket 6, sealing ring 8 is equipped between protection pipe 9 and casing 10.
The temperature sensor of the automatic telescopic of the present invention, when installation, are connected by the lower external screw thread 7 of connector sleeve 5 with equipment,
9 lower end of protection pipe is set to be contacted with measured part, spring 2 has a certain amount of compression, 9 phase of snap ring 4 and protection pipe after contact
There is a certain amount of axial displacement for connector sleeve 5, ensure that protection pipe 9 is in contact condition always with measured part, not rapid wear
Bad, temperature signal collection is accurate.
